The Philadelphia region is bracing for more severe storms and flooding as cleanup continues from the damage wrought by the remnants of Hurricane Ida.
By early Wednesday night, between 7 p.m. and 1 a.m., a line of storms is forecast to move through the region.
Valerie Meola, a meteorologist with the National Weather Service in Mount Holly, said the additional rain could spell trouble for the region.
Although there may be only an inch or two of rain from the stormfront, Meola said, its combination with previous rainfall could mean more flooding.
“The ground is pretty wet,” Meola explained, “so it’s not going to absorb the water as we expect from the storm, and that’s going to be a lot of runoff and that’s what leads to the flash flooding problems.”
Most issues are anticipated along the I-95 corridor: Philadelphia and suburbs north and west of the city. That includes Montgomery, Bucks, Chester, and Mercer counties, where flash flood guidance indicates that less than an inch in an hour would cause localized flash flooding.
Spinning winds in the atmosphere, or shear, indicates that a tornado threat also exists for Philadelphia, plus areas north and west of the city.
Meola cited wind damage as the main threat, but cautioned: “We could see some isolated tornadoes as well, so we definitely need everybody to stay weather-aware.”
Flash Flood Watch
A Flash Flood Watch will be in effect for Philadelphia, plus areas north and west of the city, late Wednesday afternoon into the overnight hours.
Rip currents at the shore
